BUCKLE.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed June 5, 1920. Serial No. 386,867.

2 0 aZZ wilom it may concern.

Be it known that I, HORACE G. HANooon, a citizen of the United States, residing at New Britain, in tile county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Buckles, of which the following is a specification.

This invention relates to a method of making buckles and to the "ticle made thereby. A buckle involving the i vention can be employed in a variety of yS in C F F L v many nelds. nor instz ice the buckle may be utilized .n conjunction with belt, or it may constitute a part of th equipment of a shoe or suspender. There are many ferent ways in which the buckle can be ployed when associated with harness. 'l t is to say the buckle is capable of general use. By the method I can produce this buckle in a quick and efficient manner and the buckle in turn will hold a strap or like part against accidental lllOTelllQllh in a stable substantial way.

In the drawings accompanying and forming part of the present specification, I have shown in detail a form of embodiment of the article comprising the invention. I also show a way of producing this article in conformity with the method. bviously I am not restricted to this disclosure. I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings:

Figure 1 is a top plan view of the frame member.

Fig. 2 is a longitudinal central section of the same.

Fig. 3 is a top plan view of the detent o" tongue member in original or arched condition.

Fig. d is side elevation of said detent blank.

Fig. 5 is a cross section of the frame and detent members in their original relation and before the detent member has been fiattened.

Fig. 6 is a cross section of the finished buckle.

Fig. 7 is a central longitudinal section or the buckle associated with a belt or strap.

Fig. 8 is a top plan View of the same.

Like characters refer to like parts throughout the several views.

The buckle as shown comprises a frame such as 2. Ordinarily this frame is cast of proper metal. As illustrated it is practis oally rectangular in plan, its side bars being longitudinally bowed and thickened somewhat at their forward ends.

In addition to the frame, there is a detent, holding or tongue member, that is denoted by 3 answering my requirements.

As shown the side bars of the frame 2 have near their forward ends the mating or registering recesses or notches at which as shown are directly opposite each other. They are open on their inner sides but closed at their ends, their tops and bottoms and their outer sides to present seats to receive for sliding movement the detent or tongue member 3.

As shown this detent or tongue member 3 is originally of longitudinally-arched form, the distance between its ends being somewhat less than that between the outer side walls of the recesses or notches at so as to facilitate the introduction of the detent or tongue member 3 into the notches or recesses. In plan the detent or tongue memer is of practically rectangular form the forward or front side bar, however, being deeper than the rear side bar 6.

Initially the metallic detent or tongue member 3 is of arched form and when in this condition its ends are easily introduced into the open sides of the registering recesses or notches 4:. l/Vhen this is effected, the detent or tongue member 3 is subjectct to depthwise pressure. This depthwise pressure flattens and thus elongates the tongue member, sufficiently to bring the ends of the tongue member well into the recesses or notches and almost in contact with the outer side walls of the two recesses r. This per mits free sliding movement of the detent or tongue member longitudinally of the frame 72 but prevents its accidental withdrawal from the recesses or notches. The buckle frame 2 has on its upward forward side the flange 8 overhanging the front portions of the recesses or notches 4 and as a result providing a substantial bearing or abutment for the detent or tongue member 3.

One end of a strap or belt 9 is fixedly connected to the rear cross bar of the frame 2 and when the detent or tongue member 3 is associated with the frame 2, the free or opposite end of the strap, belt or other part will be passed through the slot in the detent or tongue member 3 and through the loops 7 associated with the fixed part of the strap or belt. The free end of the strap or belt 9 will pass through the slot ofthe tongue member or detent 3, before entering the two loops 7 so that on longitudinal pull on the strap or belt 9, the latter will apply an up ward thrust to the forward deeper side bar 5 of the detent or tongue member 3 which in turn is taken up by the hearing or abutment 8 so as to effectually prevent accidental separation of the free end of the belt from the buckle. To disengage the belt or strap it is necessary that the belt be pulled inward thereby correspondingly moving the detent or tongue member 3 to the right in Fig. 7. What I claim is: i

1. A buckle comprising a frame furnished with side bars having longitudinally straight recesses opposite each other. the frontend of the frame having a depending flange closing the forward portion of the recesses, and a detent, the ends of which are fitted in recesses for sliding movement, the detent having a slot for the passage of the strap, the

detent forward of the slot being deeper than at'the back thereof and also extending below said depending flange and said back portionof the detent being adapted to press the strap against the back portion of said front cross bar when a forward pull is applied by the strap to said deep portion of the detent the detent moving in a straight which comprises introducing the ends of the arched detent-blank into the mating recesses and then subjecting said blank to a flattening pressure which elongates the blank and projects the end portions thereof into the recesses. I

In testimony whereof I afiix my signature.
